Roasting fresh veggies such as carrots and potatoes is one of the easiest ways to get a balanced family meal on the table. If you're eating lighter, roasted vegetables, especially potatoes and root veggies, are a perfect fit. 😏
Potatoes often get a bad reputation, but when cooked without heavy oils they're actually nutrient-rich. See my Garlic Butter Baby Potatoes in Dutch Oven recipe for details. Of course, this doesn't apply to french fries, which soak up excess oil.
The type of potato matters, too. Russet potatoes, for example, rank among the top four potato varieties by nutrient density (USDA), making them a smart choice for a weight-loss plan.
This recipe works any time of year but shines in fall and winter when root veggies are in season. It's also a festive side for holidays like Thanksgiving and Christmas. For more inspiration, pair it with my One Skillet Chicken Thighs with Wild Rice or my Simple Red Cabbage Salad for a colorful, nourishing meal.

Ingredients
- Russet potatoes. You can also use Yukon potatoes or yellow potatoes. I think russet potatoes give the best roasted potatoes flavor and texture.
- Onion. Any onion variety will be a great option here.
- Carrots. I typically peel the carrots right before using them, but you can also use a bag of pre-sliced carrots; just make sure they are cut into thick slices. You can even use baby carrots, but make sure to cut them in half or use them whole.
- Zucchini. You can also use yellow squash.
- Salt and black pepper to taste.
- Italian seasoning. Or you can make your own mix of favorite spices.
- Lemon. Cut into wedges.
- Olive oil. Or you can use avocado oil.

How to Make Oven Roasted Potatoes and Carrots with Onion and Zucchini
- Step 1: Peel the carrots, potatoes, and zucchini, then rinse under running water. Chop the potatoes into small cubes, and the carrots into medium slices.
- Step 2: Chop the zucchini into larger rounds.
- Step 3: Cut the onion into small chunks to boost flavor.
- Step 4: Place all vegetables in a large mixing bowl. Drizzle with olive oil (or avocado oil).
- Step 5: season with salt, black pepper, and Italian seasoning (or your favorite herbs). Toss to coat evenly.
- Step 6: Line a baking sheet with parchment paper and spread the veggies in a single layer. Add lemon wedges to the corners of the pan.
- Step 7: Preheat the oven to 375°F (190°C). Roast for 30-35 minutes, or until the potatoes are golden brown with crispy, charred edges. Optional: Sprinkle with Parmesan cheese before serving. Enjoy as a flavorful side dish or a satisfying vegetarian meal.
Why cut zucchini larger and carrots/potatoes smaller?
Vegetables cook at different speeds. Zucchini has a higher water content and softens quickly, so cutting it into larger chunks helps it hold its shape in the oven. Carrots and potatoes, on the other hand, are denser and take longer to cook, so chopping them into smaller pieces ensures they roast evenly and finish cooking at the same time as the zucchini.
Substitutions
- Swap zucchini with yellow squash or bell peppers.
- Use sweet potatoes instead of white potatoes for extra sweetness and fiber.
- Try red onions or shallots in place of yellow onions for a different flavor.
- Change up the herbs: rosemary, thyme, oregano, or Italian seasoning all work beautifully.
Make it a meal!
Just toss in some chickpeas, tofu, or grilled chicken. For easy ideas, try my Crispy Baked Tofu with Paprika and Turmeric or my Crispy Turmeric Roasted Chickpeas.
Storage
- Store leftovers in an airtight container in the fridge for up to 4 days.
- Reheat in the oven or air fryer at 350°F (175°C) until warmed through and slightly crispy.
- These roasted veggies don't freeze well, as they can turn mushy, so enjoy them fresh when possible.
FAQ
Yes, you can definitely roast carrots and potatoes together! They have similar cooking times, which makes them a great combo for roasting.
Most oils with a high smoke point work well for roasting, such as avocado oil, canola oil, or grapeseed oil. Personally, I prefer using extra virgin olive oil because it adds rich flavor, provides heart-healthy fats, and complements the natural sweetness of the roasted veggies beautifully.
